Tire Balancing Bead

Balance Bead For Truck
Balance beads are literally just small temperated glass balls that you insert inside a tire. They’re designed to be large enough not to fall inside the valve stem, but small enough that they’re lightweight and able to easily flow around inside the tire. The idea is that in the course of normal driving, the beads will bounce around inside the tire and end up in the right position to counteract any imbalances in the wheel.The beads are distributed around the tire as it begins to roll, through centrifugal force.

As the centrifugal force increases, the heavy spot pulls up and down on the suspension, making the beads move in the opposite direction of the downward and upward motion, through inertia.The beads continue to migrate until the complete wheel assembly is balanced.
